Maxim Integrated (MAX8570EUT+T) Display Driver, LCD Boost Step Up Converter

Product OverviewThe MAX8570EUT+T is a high efficiency LCD boost with True Shutdown mode in 6 pinSOT-23 package. This LCD step-up converter uses an internal N-channel switch andan internal P-channel output isolation switch. A unique control scheme provideshighest efficiency over a wide range of load conditions. The internal MOSFETswitch reduces external component count and high switching frequency allows fortiny surface mount components. The MAX8570 uses 110mA current limit to reduceripple and component size in low current applications. The built-in safetyfeatures protect the internal switch and downstream components from faultconditions. It also includes low quiescent current and True Shutdown mode tosave power. The MAX8570 allows user to set the output voltage between 3V and28V. This step-up converter is ideal for small LCD panels with low currentrequirements but can also be used in other applications such as LCD biasgenerators and polymer LEDs (OLED).Supply voltage range from 2.7V to 5.5VOperating temperature range from -40°C to 85°C20mA at 20V from single Li+ batteryEfficiency of 87%Up to 800KHz switching frequencyVCC shutdown current of 0.05µA at TA = 25°C and VCC supply current of 25µALine regulation of 0.1 %/V and load regulation of 0.1 %/mAApplicationsPower Management, Portable Devices, Consumer ElectronicsProduct InformationNo. of Digits: -No. of Segments: -Driver Case Style: SOT-23No. of Pins: 6PinsSupply Voltage Min: 2.7VSupply Voltage Max: 5.5VInterface Type: -Operating Temperature Min: -40°COperating Temperature Max: 85°CProduct Range: -MSL: MSL 1 - Unlimited
